The chemistry of organothallium compounds. Part III. Far-infrared spectra of halogenobis(pentafluorophenyl)thallium(III) compounds

Abstract

The far-infrared spectra (400–50 cm.^–1) of halogenobis(pentafluorophenyl)thallium(III) compounds, (R_F)₂TIX (R_F= C₆F₅; X = F, Cl, or Br), of the complexes (R_F)₂Ph₃POTIX (X = Cl or Br), and of bispentafluorophenyl-mercury have been recorded. Assignments are suggested for the thallium–halogen frequencies, and the structures of the (R_F)₂TIX compounds are discussed.
